Some faults will automatically illuminate the blue UID/Service LED on some of the components
equipped with a UID/Service LED and can be used to locate a component. A Controller Node is
ready to be removed if the UID/Service LED is solid blue and the Status LED is rapidly flashing
green. Depending on the nature of the Controller Node failure, the Fault LED might be solid amber.
NOTE:
On the other active Controller Node in the cluster, the Fault LED will be flashing, which is the
LED indicator meaning one of the other Controller Nodes in the cluster is shutdown.
8. Verify that all cables are labeled with their location.
Removal:
9. Remove cables from the Controller Node.
10. Remove the Controller Node from the enclosure.
a. Pull the gray Controller Node Rod to the extracted position out of the Controller Node.
b. When the Controller Node is halfway out of the enclosure, slide it out completely and support it
from underneath.
c. Place the Controller Node on the ESD safe mat.
11. Push in the gray Controller Node Rod to ready it for packaging and provide differentiation from the
replacement Controller Node
12. If any SFP Transceivers are installed, remove them from the failed Controller Node.
CAUTION:
To prevent damage, do not touch the gold contact leads on the SFP Transceiver.
a. Open the retaining clip on the SFP Transceiver.
b. Slide the SFP Transceiver out of the port slot and place on an ESD safe mat.
Replacement:
13. If any SFP Transceivers were removed, install the SFP Transceivers in the replacement Controller
Node.
a. Open the retaining clip on the SFP Transceiver.
b. Slide the SFP Transceiver into the port slot until fully seated.
c. Close the retaining clip.
14. Partially install the Controller Node.
a. On the Controller Node, verify that the gray Controller Node Rod is in the extracted position with
the rod pulled out.
b. Confirm that the Controller Node is correctly oriented. In the Controller Node Enclosure, the Node
Pair are installed with each Controller Node oriented 180° from each other.
